#2When I saw the title I was prepared for a great hack. Something that truly belonged on Hacker News. But this seems a lot more lame.
"I made lighting controlled by a ESP32, then put it inside the brush and connected the button to it."
But reading the twitter replies further down the chain, it seems the toothbrush sends data to the charging base, and the ESP resides there and analyzes the signals sent to the base? Much more interesting. Twitter's character limit really killed this post.
Unrelated, all the hashtags and @s make Twitter quite hard to read. The @ and # characters should be hidden for readers.

#3Coincidentally, I bought an ESP32 (ESP-WROOM-32 Rev1)[0] last month, and have a bluetooth toothbrush and a couple of Amazon Smart Plugs. I guess you could make your own brushing compliance system with an alarm, and add a camera plus CV to detect an absence of motion to prevent basic cheating.

Can help fill in some of the blanks for you. The toothbrush has bluetooth. Its bluetooth advertisement contains information about its operating state (running, idle, etc.), mode (brush, daily clean, etc.), pressure and some other things.
The ESP32 chip scans bluetooth, detectes these advertisements, parses them and extras the data. It then sends it over to home-assistant.io which can use the data to trigger actions on any other connected device.

"because I am stuck at home and bored out of my mind" is a plausible theory to me, though really, I find myself asking the same question about why the hell a toothbrush needs to connect to anything but power in the first place. The toothbrush company's page on the virtues of their Bluetooth toothbrush is not very compelling IMHO: https://oralb.com/en-us/why-switch/

Of course it doesn't. They've saturated the market though, so it gives them something to sell to people who already have a power toothbrush.
